Hi,
This one is not liquid damaged, fixed charging circuitry and it's back to life,
However, only one slot (bottom) is working.
If I insert a ram stick in the top slot, it will give 3 bips errors.
If I put no ram stick on both slots, I have the normal one bip missing ram.
Only If I use the bottom slot it works fine.
I will not bother too much and just max out the working slot,
But I wonder what rail can I check that is exclusive to the non working slot?
Thanks

If it's not corner solder related it's likely a bad RAM slot and no repair for it. As 2informaticos said, verify solder points for top ram slot.
